Thanks, Stéphane! And I assume, there is no way to narrow that down (somewhere in
affinis,
setifemur,
urbana,
humeralis?)?

setifemur and
humeralis have a yellow scutellum. I need to see the katepisternal for other species.

thanks! I assume 'kapisternal' is some kind of bristle. Google gives exactly 2 hits for that term B), one in Czech and one from bugguide.net.

here is my definition utilizing my etymological knowledge (I study much more than nature):
a lower (kat- [down] + episternum) lateral division of the thorax
as opposed to the proximate upper (an-) episternal division of the thorax
katepisternum (adjective=katepisternal, id est, katepisternal seta[-e])
sternopleuron (adjective=sternopleural, id est, sternopleural seta[-e])
the term sternopleuron is used in most German text instead.

unfortunately, the katepisternum is not viewable in any of your additional photos.

a lateral view is necessary and sometimes from below.

I think now that you were pointing out a typo by Stephane, yes? I wondered why you would surround the term in quotes. I was too tired to log back in and ask about it. I figure Stephane must have corrected the misspelling. If this was the situation, thenThanks for being a good sport Juergen :)
I was tired last night. I spent the day examining a
Pollenia specimen. My mind was sleeping long before my body :)
